Description

{A DEVICE GENERATING MAGNETIC FIELD FOR TREATMENT OF A PATIENT}

The present invention generally relates to devices and methods for using the influence of magnetic and induced electric fields on biological structures.

Known devices suffer from limitations in key parameters that do not allow satisfactory improvement of visual appearance. As a result, new devices are needed.

The treatment device generates a time-varying magnetic field for the treatment of cellulite, reducing fat cells and/or increasing muscle volume or strength. Therapeutic devices optimize energy use, increase efficiency and provide new treatments. Magnetic impulses can be generated in monophasic, biphasic or polyphasic regimes. The coils are made of individually insulated wires which significantly reduce eddy currents. The coil can be flexibly attached to the casing of the applicator. The coil may be cooled by an air mover on the circumference of the coil. The coil may optionally be a planar coil.

A time-varying magnetic field induces muscle contractions at higher repetition rates, and the contractions become stronger. Treatment may be used to reduce the number and/or volume of fatty cells and improve the visual appearance of the treated body area through targeted muscle contraction. Additionally, strong muscle contraction at higher repetition rates causes mechanical displacement of all layers near the contracted muscle. This method results in remodeling and/or neogenesis of collagen and elastin fibers.

Although the operations of the subject matter are described herein as a series of steps in a particular order, it is understood that the steps of any method of the subject matter may alternatively be performed in a different order, unless explicitly stated otherwise. In some embodiments, some or all of the steps may be repeated.

Terms

The biological structure is at least one nerve, neuromuscular plate, muscle fiber, fat cell or tissue, collagen, elastin or skin.

A body region includes a muscle or muscle group, glutes, saddlebags, love handles, abdomen, buttocks, thighs, arms, extremities, and/or any other tissue except the pelvic floor.

A muscle includes at least one of a muscle fiber, a muscle tissue or group, a neuromuscular plate, or a nerve innervating at least one muscle fiber.

Impulse refers to magnetic stimulation, i.e. the generation/application of a magnetic field. This is the period of time when the switch is flipped. The impulse may consist of a single-phase time-varying magnetic field, a biphasic time-varying magnetic field, or a multi-phase time-varying magnetic field sufficient to induce muscle contraction.

A pulse refers to a treatment cycle consisting of one impulse and a time period in which no magnetic field is generated or is insufficient to induce muscle contraction, i.e. the time period from the rising/falling edge between two impulses to the next rising/falling edge. .

Repetition rate refers to the frequency at which pulses are emitted; This is derived from the time period of the pulse. This is the same frequency at which the switch switches to the on state.

Hardware panel refers to at least one hardware component used to control treatment. The hardware panel includes at least one of an input interface for inputting treatment parameters by an operator and a processing unit to control the treatment.

The treatment device may include at least one magnetic field generating device, such as a coil. Alternatively, the treatment device may include a plurality of coils. At least one applicator may include at least one coil.

The coil may be composed of litz-wire, with each wire being separately insulated. Each individual conductor is coated with a non-conductive material so that the coil consists of multiple insulated wires. The insulation of the wire is a significant improvement, as it leads to a significant reduction in induced eddy currents. The small diameter of the wire significantly reduces self-heating of the coil and thus increases the efficiency of the treatment device.

Dynamic forces created by current pulses passing through the coil's wires cause vibration and unwanted noise. The wires of the coil can be impregnated under pressure to remove air bubbles between the wires. The space between the wires can be filled with a suitable material that causes integrity, preservation and electrical insulation of the system. Suitable rigid impregnating materials such as resins and elastic materials such as PTE may also be used. By means of the coil provided as a solid material, vibrations and resonances caused by the movement of the individual insulating wires are suppressed. Therefore, noise is reduced.

The coil can be used with a hand held applicator; For example, built-in applicators within chairs, beds; Or it may be attached to the case of the applicator, for example as a free-standing applicator on a mechanical fixture. The treatment device may preferably include a human machine interface (HMI) for displaying and/or adjusting treatment parameters. The HMI may include at least one button, knob, slide control, pointer, or keyboard. Alternatively, the HMI may include an audiovisual input/output device, such as a PC including a touchscreen, display unit, input unit, and/or graphical user interface.

At least one fastening point ensures connection of the coil to the casing such that a major portion of the coil and a major portion of the casing of the applicator are spaced apart. To allow air to flow easily, the gap should be at least 0.1 mm. Alternatively, the gap may be at least 1 mm, most preferably at least 5 mm, to enable cooling medium flow. The gap between the coil and casing can be used for spontaneous or controlled cooling. The coil may be cooled by a fluid, such as air, water or oil. The fastening points eliminate vibrations of the wire that may be transmitted to the casing of the applicator, thus reducing the noise of the treatment device.

Figure 1 is a cross-section of the applicator allowing better flow on the lower and upper sides of the coil and therefore more efficient heat dissipation. The treatment device comprises a coil (1), circuit wiring (2) and fastening points (3) for connecting the coil to the casing of an applicator (not shown). The fastening point 3 is preferably made of a flexible material, but rigid materials could likewise be used. The attachment portion may be provided by an elastic material such as silicone, gum or other flexible means. The fastening point 3 can be located on the outer circumferential side of the coil. However, these fastening points can be placed on the lower or upper side of the coil.

Fastening points 3 connect the coil to the case of the applicator at at least one point. Alternatively, the coil may be attached to the casing of the applicator via a circular rigid member surrounding the coil. The outer circumference of the circular rigid member may be attached to the casing of the applicator. The coil may be flexibly attached to the inner circumference of the circular rigid member by at least one attachment point. Alternatively the coil may be attached to the circular member along its entire circumference.

The fastening points 3 hold the coil and the main part of the case of the applicator apart so that a fluid (which can be air or any liquid) can flow between them. At least one blower 4 can be arranged around the circumference of the coil or perpendicular to the coil. The blower can be a device of any known type for directing a fluid, for example external air, into the case of the applicator. The blower may be, for example, a fan or a suction pump. In another embodiment, the outside air may be cooled before being introduced into the case. A blower may have an inlet disposed around the circumference of the coil to introduce air and remove heat from the coil. A connecting tube (not shown) may ensure connection of the applicator with the energy source and/or control unit of the treatment device. The connecting tube may also comprise a conduit for a fluid, for example pressurized air.

Arrow (5) indicates air flow through the applicator. This arrangement of the blower allows air to bypass the coil from the upper and lower (patient's) sides. The outlet may preferably be located on the top side of the casing. The outlet may include a plurality of holes allowing unimpeded removal of the heated cooling medium from the casing of the applicator. By placing the blower around the circumference of the coil instead of at the top/bottom of the coil, the blower 4 does not interfere with flux peaks and its life and reliability is increased.

2A is an exemplary embodiment of the casing of an applicator. The schematic diagram includes a casing (6) which may comprise an outlet (7) arranged preferably on the upper side of the casing (6). The applicator may further include a handle 8 on the upper side of the casing. Handle 8 can be used for manual positioning of the applicator. The connecting tube 9 ensures the connection of the applicator with the energy source and/or control unit of the treatment device, as well as the connection to the source of fluid. However, the conduits of fluid 10 may also be connected separately.

The connecting tube 9 may include a connector for connecting the applicator to the treatment device. The connector can be connected to the connecting tube 9 either at its first end between the connecting tube 9 and the casing 6 or at its second end between the connecting tube 9 and the case of the treatment device. The applicator comprising the coil can be connected to the magnetic treatment device independently on the positioning arm, preferably by means of a connector. The connector may be any type of electromechanical connector that provides electrical communication of the applicator to the treatment device. Mechanical connection may be provided by additional latching mechanisms known in the art. The applicator may be replaced by another applicator. Each applicator may include a unique identifier for the applicator for communication with the control unit of the treatment device. Communication can be done through NFC, RFID, ZigBee, IRDC, Bluetooth or wired communication. Alternatively, the applicator may include a mechanical identifier, such as a specific combination of a plurality of pins, in a pattern.

Figure 2B shows a side view of an exemplary embodiment of a concave applicator. The applicator includes a handling member (8) as a recess (11) of the applicator. The recess may enable insertion of a positioning member, such as an adjustable length belt. The handling element 8 can also be used for manual positioning of the applicator. The handling member 8 can preferably be in the center of the applicator. The handling member 8 may be on the upper side of the casing 6 of the applicator. The concave portion 11 may have one side open.

Figure 2C shows a top view of the concave applicator. The applicator may preferably include a marker 12 over the center of the coil. Marker 12 allows the operator to comfortably position the applicator. The marker may be a recess within the surface of the casing. Alternatively the marker may cover a different surface. Alternatively, the top side of the casing may include two colors. One color may be on the coil to enable precise positioning of the applicator. The remainder of the applicator may be a different color.

Alternatively, the applicator may be configured to fit any area of the patient's body, including the legs, arms, buttocks, or abdomen. The applicator may be molded to correspond to an area of the patient's body, such as a limb. The shape may include recesses to maintain the body area in the correct treatment position. The body area applicator (hereinafter referred to as BR applicator) may have a plurality of sizes configured to fit the patient's body area depending on the patient's needs.

The BR applicator may include a first portion on the patient side, ie the first portion may be in contact with the patient. The BR applicator may include a second portion on the side opposite the first portion, ie the second portion may be farther from the patient than the first portion.

2D and 2E show exemplary embodiments of the BR applicator 44 used on the extremities. The first side portion 45 may be at least partially concave. The first side portion 45 may be V-shaped or preferably U-shaped. The radius of curvature of the first side portion 45 is at least 1 mm, preferably in the range from 10 to 750 mm, more preferably in the range from 50 to 500 mm, most preferably in the range from 60 to 250 mm or up to 1 m. It can be. The radius of curvature may correspond to the size of the limb. The at least partially concave first side portion 45 may be part of a total curvature of an oval or circular shape. The first side portion may be at least a 5° section of total curvature, preferably in the range of 10 to 270°, more preferably in the range of 30 to 235°, even more preferably in the range of 45 to 180°. range, most preferably between 60 and 135 degrees. The first side portion may be configured to maintain the limb within the first side portion during treatment. The first side portion may provide stable equilibrium for the treated body area. Although the limb may be moved by muscle contraction, the patient's limb may be maintained within the first side portion. Lateral movement and/or rotation of the limb may be limited by the first lateral portion and the limb may be in a stable position. Rotational movement about the BR applicator may be limited by attaching the BR applicator to a body area.

The second side portion 46 may preferably be on an opposite side of the BR applicator 44 relative to the first side portion 45 . The second side portion 46 may be substantially planar. The second side portion may be configured to hold the applicator on a patient support on which the patient may lie during treatment. In an exemplary embodiment, the second side portion may include a positioning mechanism for manually adjusting the position of the coil within the BR applicator.

BR applicator 44 may be attached to the patient by a positioning mechanism, such as an adjustable belt, which may be flexible. In an exemplary embodiment, an adjustable belt may be secured to a recess/cutout 47 at the first end 48 of the first side portion 45. The second end 49 of the first side portion 45 may include a recess 50 and a clip mechanism for securing an adjustable member within the recess 50 . Clip 51 can move around pin 52 clockwise or counterclockwise. The clip may be biased by a spring. Alternatively, the clip may be locked by a suitable locking mechanism or by any other movement restraint method. The clip may include a fastener 53 on the lower side of the clip to secure the correct length of the adjustable member. The fastener may be a hook-and-loop fastener, such as a Velcro fastener, a pin type, etc.

In alternative embodiments, the BR applicator may include a counterpart to the portion containing the coil. The at least one counterpart portion may be configured to maintain the BR applicator in a static position relative to the body region. The counterpart portion may preferably be arranged on opposite sides of the body area. The counterpart part may be attached to the part containing the coil by a flexible member or a belt of adjustable length. Alternatively, the mating part may be attached by a hinge, by a suitable locking mechanism such as a clip, spring clip, pin type, etc., or in any other way. The portion comprising the counterpart and the coil may preferably at least partially surround the limb.

The coil may not be planar. The coil may be conical, convex and/or concave, for example biconvex, plano-convex, positive meniscus, negative meniscus, plano-concave or biconcave. The non-planar geometry of the coil may allow for a larger cooling surface, and cooling may be more efficient. Additionally, the non-planar shape may shift the peaks of the magnetic field closer/further to/from the patient, or the profile of the magnetic field may be adjusted by the non-planar shape of the coil. Treatment with non-planar coils may be more efficient than treatment with planar coils. The magnetic flux density generated by the coil, sufficient to cause muscle contraction, may be lower than that of a planar coil. Heat dissipation can be improved by a larger surface cooled by the cooling medium. Power consumption can be lower.

The applicator can be made of biocompatible materials, such as fluid-sterilizable plastics, which enable high hygiene standards.

A static position of at least one applicator may be provided by a positioning member. The positioning member may for example be an arm or an adjustable flexible belt. The positioning member may ensure intimate attachment of the applicator within the vicinity of a body area or alternatively direct contact with the patient. Direct contact with the patient may include direct contact with the patient's skin, i.e., contact of the applicator containing the coil with the patient's skin, or contact of the applicator with the patient's skin through clothing or any separate object. there is. Alternatively, the positioning member may secure the applicator containing the coil so as not to contact the patient's skin.

The positioning member may include a buckle for adjusting the length of the belt. The applicator may be placed within a predefined location on the belt. Alternatively, the applicator may be molded to be movable along the positioning member, for example the shape of the applicator may preferably be concave, for example V-shaped or U-shaped. The positioning member can insert itself into the recess of the applicator. The position of the applicator can be adjusted by limited movement along the positioning element, since the positioning element can be used as a guiding element. However, the applicator may not be fixed to a specific static position. The position of the applicator can be dynamically adjusted during treatment depending on the patient's needs. The position of the applicator can be adjusted manually by the operator or automatically by the treatment device. In one example embodiment, multiple applicators can be used to treat larger body areas, such as the buttocks, abdomen or thighs, or pair muscles.

The positioning member may be rigid and the applicator may be suspended from the positioning member. The positioning arm may include a plurality of movable members that may be articulated. The movement of the at least one movable member may be translation and/or rotation. The positioning arm may include a joint that provides at least one degree of freedom for the at least one positioning arm. In a more preferred embodiment, the positioning arm comprises multiple degrees of freedom, for example two, three or more degrees of freedom. An example of such a positioning arm may be an open kinematic chain comprising at least two, more preferably four and even more preferably six degrees of freedom. The fixed frame of the open kinematic chain may be the main body of the treatment device. The endpoint of the kinematic chain may be an applicator and/or coil.

Figure 3A shows an exemplary embodiment of a treatment device 13 comprising a positioning arm 14 for positioning an applicator (not shown). The treatment device 13 may include a wheel 15 for moving the treatment device. The wheel can be propelled. The plurality of wheels may preferably be external to the bottom protrusion of the body of the treatment device to provide improved stability of the treatment device.

Figure 3b shows a positioning arm 14 comprising movable links 16 connected by joints 17 enabling two, four and most preferably six degrees of freedom. Three of these joints can be locked by a locking mechanism such as a screw mechanism. The positioning arm may include a support member for attaching the connecting tube to the positioning arm. The support member may maintain the connecting tube in an orientation parallel to the positioning arm.

Positioning arm 14 is attached to treatment device 13 (not shown) at a first end of positioning arm 18. In an exemplary embodiment, the positioning arm is attached to a circumferential side of the case of the treatment device. The positioning arm further comprises a hollow sleeve (19) at the second end (20). The sleeve 18 includes a gap 21 for removably attaching the applicator 6 to the positioning arm 14 .

The positioning arm may include a member 43 for guiding the connecting tube.

Figure 3c shows an applicator 6 that can be removably attached to the positioning arm 14. Connection of the applicator 6 to the positioning arm is made possible by a locking mechanism. The applicator 6 includes a latching member 22 that is biased by an elastic member. The latching member 22 is configured to fit into the gap 20 in the hollow sleeve 18 at the second end of the positioning arm. The applicator 6 is attached to the positioning arm 12 by inserting the applicator 6 into the sleeve 18 and locking the latching member 22 within the gap 20. The applicator can be removed by pressing the latching member and pulling the applicator out of the sleeve.

4A and 4B show exemplary embodiments of circuitry for providing high power pulses to a coil. The proposed circuit involves charging an energy storage device, such as a capacitor, from an energy source, repeatedly switching a switching device, such as a switch, and discharging the capacitor with a coil to generate a time-varying magnetic field. . Either the energy source or the switch, or alternatively both the energy source and the switch, may be regulated by control unit 42. Control unit 42 may regulate and/or make tunable the parameters described herein to generate a time-varying magnetic field for treatment. The control unit 42 can disable the generation of the magnetic field by the coil. Adjustments can be performed by preset protocols via HMI or by the operator/end user of the device.

Referring to Figure 4A, a circuit for providing high power pulses to a treatment device includes a series connection to a switch 23 and a coil 24. Switch 23 and coil 24 are connected together in parallel with capacitor 25. Capacitor 25 is charged by energy source 26, and capacitor 25 is then discharged through switch 23 into coil 24.

During the second half cycle of the LC resonance, the polarity on the capacitor 25 is reversed compared to the energy source 26. In this second half cycle, there is a collision between energy sources 26 where the voltage on the positive and negative terminals is typically several thousand volts. Capacitor 25 is also charged to positive and negative voltages, typically thousands of volts. As a result, there is twice the voltage of the resulting energy source 26 in the circuit. Accordingly, the energy source 26 and all parts connected within the circuit are designed for high voltage loads. Accordingly, a protective resistor and/or a protective circuit 27 must be placed between the energy source 26 and the capacitor 25.

Figure 4b shows a circuit for providing high power pulses for improved functionality of the treatment device. Coil 28 and capacitor 29 are connected in series and placed in parallel with switch 30. Capacitor 29 is charged through coil 28. To provide a pulse of energy, a controlled short circuit of the energy source 31 occurs via a switch 30 . In this way, a high voltage load at the terminals of the energy source 31 is avoided during the second half-cycle of the LC resonance associated with the known device. The voltage on the terminals of the energy source 31 during the second half cycle of the LC resonance is the same voltage as the voltage drop on the switch 30.

The capacitance of the capacitor is in the range from 5 nF to 100 mF, preferably in the range from 25 nF to 50 mF, more preferably in the range from 100 nF to 10 mF, even more preferably in the range from 1 μF to 1 mF, most preferably in the range from 5 to 5 mF. It can be in the range of 500 μF.

The capacitor can be charged to a voltage of at least 100, 250, 500, 1000, 1500, 2500 V or more.

The capacitor can provide a current pulse discharge of at least 100, 250, 500, 750, 1000, 1500, 2000 A or more. The current may correspond to the value of the peak flux density of the magnetic field generated by the coil.

Switch 30 may be any type of switch, such as a diode, MOSFET, JFET, IGBT, BJT, thyristor, or a combination thereof. Depending on the type of component, the load on the energy source 31 is reduced to a few volts, for example 1-10 volts. As a result, there is no need to protect the energy source 31 from high voltage loads, for example thousands of volts. The use of protective resistors and/or protective circuits is reduced or eliminated. This design simplifies the circuitry used, increases the efficiency of energy use, and provides greater safety.

The inductance of the coil is up to 1 H, or in the range from 1 nH to 500 mH, or in the range from 1 nH to 50 mH, preferably in the range from 50 nH to 10 mH, more preferably in the range from 500 nH to 1 mH, most preferably. may range from 1 to 500 μH.

Figure 5 shows the bottom projection of an exemplary embodiment of a circular planar coil. The coil has an outer diameter (D); internal diameter (d); It is characterized by dimensions including an inner radius (r) and an outer radius (R). The coil is further characterized by areas A1 and A2.

Area A1 is associated with dimensions r and d. Area A1 does not contain any windings. Area A1 can be represented by a core. The core may preferably be an air core. Alternatively, the core may be a permeable material with high field saturation, for example an iron alloy such as Parmenjour, permalloy or silicon iron/steel.

The dimensions r and R can be used to achieve a convenient shape of the generated magnetic field.

In an exemplary embodiment, the coil diameter (D) is 100 mm and dimension r is 10% of dimension R. In this exemplary case dimension R is 50 mm and dimension r is 5 mm.

Alternatively, the windings may contain a gap between each other. The gap may be up to 50, 25, 15, 10, 5, 1, 0.5 or 0.1% of the dimension (R-r).

The total coil surface, A1+A2, may range at least 1 cm ² . The total coil surface may be up to 8000 cm ² , or in the range of 5 to 8000 cm ² , preferably in the range of 10 to 2000 cm ² , more preferably in the range of 20 to 1000 cm ² , and most preferably in the range of 50 to 500 cm ² It may be a range.

Core area (A1) may range from 0.01% to 99% of the total coil surface. Alternatively, the core area (A1) ranges from 0.05% to 95% of the total coil surface, preferably in the range from 0.5 to 90%, more preferably in the range from 1 to 75%, more preferably in the range from 5% to 60%, Most preferably, it may range from 10% to 40%.

The total weight of the coil may range from 1 gram to 50 kg. The total weight of the coil is preferably in the range of 10 grams to 25 kg, more preferably in the range of 0.1 to 15 kg, even more preferably in the range of 0.5 to 10 kg, most preferably in the kilogram level, e.g. It may be 1 kg, 2 kg, 3 kg, 5 kg or more.

Magnetic fluence is defined by Equation 1.

Here, MF is the magnetic fluence [T·cm ² ]; B _PP is the maximum peak-to-peak magnetic flux density generated by coil [T]; A _MFGD is the area of the coil [cm ² ]. The coil has a temperature in the range of 5 to 60000 T·cm ² , or in the range of 60 to 60000 T·cm ² , or in the range of 70 to 60000 T·cm ² or in the range of 5 to 40000 T·cm ² , preferably in the range of 70 to 60000 T·cm 2 . a time-varying magnetic field of magnetic fluence in the range of 20000 T·cm ² , more preferably in the range of 75 to 15000 T·cm ² , even more preferably in the range of 80 to 2000 T·cm ² or up to 60000 T·cm ² can occur.

The winding magnetic fluence is defined by Equation 2.

Here, WMF is the winding magnetic fluence [T·cm ² ]; B _PP is the maximum peak-to-peak magnetic flux density generated by coil [T]; A ₂ is the winding area of the coil [cm ² ].

The coil preferably has at least 5, 10, 15 or 20 T·cm ² , or in the range of 5 to 40000 T·cm ² , or in the range of 40 to 40000 T·cm ² , or in the range of 40 to 20000 T·cm ² . is in the range of 50 to 10000 T·cm ² or in the range of 75 to 7500 T·cm ² , more preferably in the range of 100 to 5000 T·cm ² or 150 to 2750 T·cm ² , even more preferably in the range of 200 to 200 It is possible to generate a time-varying magnetic field with a winding magnetic fluence in the range of 2000 T·cm ² , or from 275 to 1500 T·cm ² , or up to 40000 T·cm ² .

According to some embodiments, the coil may be round, circular, oval, square, rectangular, or any other shape. Alternatively, the coil may be a solenoid.

Figure 6 shows the exponential voltage drop within the capacitor. Energy savings during treatment may be characterized by a reduced voltage drop in the capacitor between the first, second and subsequent resonant oscillation maxima. The magnitude of individual voltage oscillations decays exponentially until energy balance is established. This makes it possible to increase the maximum possible frequency/repetition rate of the magnetic pulses, since the frequency/repetition rate depends on the rate at which the capacitor can be recharged. Because the capacitor is recharged by the amount of energy lost during the previous pulse, the frequency/repetition rate of the treatment device can be increased to hundreds of magnetic pulses per second without the need to increase the input power. The voltage drop between any successive amplitudes shall not be higher than 45, 40, 30, 21, 14 or 7%.

The treatment device may include at least one sensor for measuring operating parameters such as voltage, current or phase.

The active treatment cycle may be referred to as a train. T ₁ lasts 2s. Therefore, the target biological structure is treated by 20 magnetic pulses. Passive treatment continues for cycle T ₂ . T ₂ lasts 18 seconds. After T ₂ , cycle T ₁ is repeated. In this exemplary treatment, the cycle, including active and passive cycles, lasts 20 seconds. Active treatment followed by passive treatment may be referred to as a burst, i.e. a burst comprises one train and a cycle with no magnetic field applied to the patient. Burst time (T ₃ ) is equal to T ₁ + T ₂ . T ₂ may last for the period of at least one magnetic pulse in the train. A train contains a plurality of pulses, i.e. at least two pulses. Bursts can be applied repeatedly to the patient. The burst repetition rate may range from 100 Hz to 0.01 Hz, more preferably from 50 Hz to 0.02 Hz or most preferably from 10 Hz to 0.05 Hz.

In an exemplary embodiment, the treatment device includes a plurality of applicators. Preferably two applicators can be used. The treatment device may include two independent circuits for generating a magnetic field and a connection to a power grid. Each independent circuit may include a power source, switches, capacitors, and coils. Alternatively, one energy source can be common to multiple magnetic field generating circuits.

Alternatively, at least one capacitor can provide energy to the plurality of coils. Alternatively, both circuits may include a common power supply.

Circuit 32 may generate a time-varying magnetic field independently of circuit 37. The treatment device may generate a magnetic field by one circuit while the second circuit is turned off, i.e. circuit 32 may generate a magnetic field while circuit 37 is turned off, or circuit 32 may generate a magnetic field while the second circuit is turned off. While turned off, circuit 37 may generate a magnetic field.

Alternatively, circuit 32 may generate a magnetic field of the same therapeutic parameters as the magnetic field generated by circuit 37. Both circuits can be configured individually or synchronously. Each of the plurality of coils 36, 41 can provide magnetic field treatment simultaneously without the need to alternate coils during a single treatment.

All coils of the plurality of coils can generate a magnetic field during treatment without any operator input. Treatment may include multiple impulses, pulses, trains, bursts, or periods of time during which no magnetic field is applied to the patient or when the flux density of the magnetic field is insufficient to induce eddy currents in the patient to induce muscle contraction. there is.

The control unit allows assembling magnetic pulses into various shapes (eg triangular, rectangular, trapezoidal, exponential). The impulse frequency of the impulse may range from hundreds of Hz to hundreds of kHz, more preferably from a few kHz to tens of kHz, most preferably up to 10 kHz. However, the repetition rate of the impulses may be up to 700 Hz, more preferably up to 500 Hz, most preferably in the range from 1 to 300 Hz, for example at least 1, 5, 20, 30, 50, 100, 140 or 180 Hz. It can be reached. The flux density of the magnetic field may be at least 0.1, 0.5, 0.8, 1, 1.5, 2, 2.4 or up to 7 Tesla on the coil surface, or in the range of 0.1 to 7 Tesla or in the range of 0.5 to 7 Tesla (equivalent to 70000 Gauss). It can be. The treatment/continuous treatment may last several seconds, for example at least 5, 10, 30, 60, 120 or 240 seconds, for example at least 20, 30, 45, 60 minutes or more. The impulse period may range from 3 μs to 10 ms or longer, or alternatively from 3 μs to 3 ms or alternatively from 3 μs to 1 ms. The impulse duration may be less than, for example, 3, 10, 50, 200, 300, 400, 500, 625, 1000, 2000 or 3000 μs. Alternatively, the impulse period may be in the range of ms. The total power consumption may be less than 1.3 kW, for example at least 150, 250 or 500 W, to generate a flux density sufficient to induce muscle contraction. Energy conversion efficiency may be at least 10, 25, 50, or 80%.

The derivative of magnetic flux density is defined by Equation 3.

Here, dB is the magnetic flux density derivative [T]; dt is the time derivative [s]. The maximum value of the magnetic flux density derivative is at most 5 MT/s, preferably 0.3 to 800 kT/s, 0.5 to 400 kT/s, 1 to 300 kT/s, 1.5 to 250 kT/s, 2 to 200 kT/s. , 2.5 to 150 kT/s, 4 to 150 kT/s, 5 to 150 kT/s. In an exemplary application, the maximum value of the magnetic flux density derivative may be at least 0.3, 0.5, 1, 2.5, 3.2, 5, 8, 10, 17, 30 or 60 kT/s. The value of the magnetic flux density derivative may correspond to the induced current within the tissue.

The magnetic flux density derivative may be determined within an entire period of the magnetic signal and/or within any segment of the magnetic signal.

The device may enable continuous therapy and continuous magnetic therapy, wherein the set of magnetic flux densities and frequencies/repetition rates of the magnetic pulses is determined by the operating temperature on the casing of the device, which operates at an ambient temperature of 30 °C, independent of the duration of therapy. does not cause the temperature to exceed 60 °C, preferably 56 °C, more preferably 51 °C, even more preferably 48 °C and most preferably 43 °C.

The treatment device may include a communication module coupled to a control unit. The communication module may collect service data of the treatment device, such as number of pulses, hardware or software errors, etc. The communication module can communicate via a datalink with a remote control station, for example a server, a central computer or a main control center. The data link can be any type of communication link, such as wireless such as a wireless Internet connection, IRDC, Bluetooth, dial-up connection, Wi-Fi, GSM, PCS, or wired such as Ethernet. Data can be processed by software and displayed for further analysis. Data may be displayed in a mobile application. Alternatively, service data may be evaluated and optional notifications may be provided to end users of the treatment device. In an example application, the data may correspond to treatment credits (corresponding to wear and tear of a treatment device or part thereof) and may be decremented after each treatment. The treatment device may disable generating magnetic fields after the credits are exhausted. Alternatively, the treatment device may disable generating the magnetic field after reaching a predetermined number of treatments.

Electrical currents can be induced within the treated biological structure during pulsed magnetic therapy. Due to high values of magnetic flux density, biological structures can be targeted and treated more specifically. The distribution of magnetic fields is uniform in biological structures. Particles within biological structures (e.g. atoms, ions, molecules, etc.) are affected by magnetic fields and the permeability of cell membranes may also increase.

Due to the increased permeability of the cell membrane, pulsed magnetic fields can induce the following effects: at least muscle contraction; A decrease in adipose tissue-volume and/or number of adipocytes, including an increase in the apoptotic index; Cellulite reduction; New generation and/or remodeling of collagen and/or elastin fibers, i.e. increased collagen and/or elastin; Improving skin elasticity and/or skin texture; Relieves sagging skin; Waist reduction. Additional magnetic treatment may improve circulation of blood and/or lymph and improve local and/or adipose tissue metabolism. Treatment with time-varying magnetic fields may also cause muscle hypertrophy and/or hyperplasia; Reduces rectus abdominis separation (abdominal separation); Increase fat and/or basal metabolism; and/or reduce visceral fat. The treatment effects include contouring, circumferential reduction, core strengthening, body contouring, body sculpting, core shaping, muscle shaping, muscle shaping, reduction of skin sagging, muscle strengthening, muscle elasticity, muscle firming, muscle increase, and muscle sagging relief. , for example, may be known as butt lifting. Additionally, treatment with time-varying magnetic fields can cause body shaping to improve the visual appearance of the treated body area. Body shaping may include muscle hypertrophy, muscle hyperplasia, cellulite reduction, and/or fat cell reduction.

In other aspects, improvements in muscle functionality and/or appearance may be achieved with results similar to physical exercise. This result can be achieved by application of a high magnetic flux density to an area of the body and at least induction of muscle contraction. Higher values of applied magnetic flux density can result in stronger muscle contractions. Repetitive applications can be more efficient than standard exercises in fitness because fitness machines only strengthen isolated muscles. These results can be achieved in a very short period of time with minimal treatment time.

According to the method, factors that improve the visual appearance of the body include: treatment of the primary muscles, such as the gluteus maximus; Treatment of internal muscles, which can be made possible by high values of magnetic flux density; Non-contact application of magnetic flux density, which can also be applied through clothing; Stronger muscle contraction due to higher values of magnetic flux density; Higher quality of muscle targeting; Treatment may not be affected by small movements during treatment; The treatment time period may be shortened due to higher values of flux density and/or higher repetition rates; This includes that delays cannot occur.

According to an exemplary application, treatment may be initiated by turning on the treatment device. An applicator containing a coil may be placed on a patient. The magnetic flux density can be set as the highest magnetic flux density value acceptable to the patient. The highest magnetic flux density value acceptable to a patient may be a value that is sufficient to cause muscle contraction and may not cause pain to the patient. Additionally, the exact treatment location can be found by the operator. The correct treatment location can be found by moving at least one applicator over a target area of the patient's body. Alternatively, multiple applicators can be moved simultaneously to establish the correct treatment position. The correct treatment location is the location where the induced current causes the strongest muscle contraction. At least one applicator can be held by a positioning member in a static position relative to the patient. Treatment may be initiated, i.e. a time-varying magnetic field may be applied to a body area for a predetermined treatment period.

In a preferred application, the magnetic field generated by the treatment device is directed to areas of the body prone to developing fat accumulation and/or developing cellulite, such as the thighs, saddlebags, buttocks, abdomen, belly area or bra fat area or arms. It can be applied to any area. Fat accumulation can be influenced by the number and/or volume of fat cells. The plurality of coils may apply a time-varying magnetic field to different body areas or to different locations of one large body area, such as the abdomen or buttocks.

Magnetic fields can treat peripheral nerves within the treated body area. Alternatively, peripheral motor neurons that innervate hundreds of muscle fibers can be selectively targeted. Muscle contractions of entire muscle groups innervated by specific nerves or plexuses can also be induced.

Due to the high flux density of the generated magnetic field, supermaximal muscle contractions can occur. Supermaximal contractions cannot be achieved voluntarily. Muscles can naturally change as they adapt to the muscle stress caused by supramaximal contractions. Therefore, muscle strength and/or volume may increase. Increased muscle strength and/or volume may be achieved by muscle fiber hypertrophy and/or muscle fiber hyperplasia. Muscle tension may also increase. These structural changes can last longer than regular exercise.

One application of time-varying magnetic fields to improve the visual appearance of a body area could be the treatment of muscles with magnetic flux density to reduce cellulite. The magnetic flux density may be transmitted through the skin to the neuromuscular plate and/or to the nerve innervating at least one muscle fiber. An electric current can be induced within a target biological structure to cause at least muscle contraction. At the very least, muscle contraction can cause movement of the epidermis and corresponding biological structures. Additionally, at least muscle contraction can improve blood circulation, either on its own or through movement of nearby muscle muscles containing fibrous septa. Additionally, because muscle contraction can move the fibrous septa, blood and/or lymph circulation can be improved in the epidermis corresponding to these layers. Additionally, local and/or adipose tissue metabolism may be improved.

By the present method, muscle contraction induced by the applied magnetic flux density can help to tone the muscles and provide a more attractive appearance. As muscle structures are treated by time-varying magnetic fields, the entire limb can be moved due to the high power of the magnetic therapy. Nevertheless, the method is not limited to application to the extremities, the method can be used with any muscle, for example the gluteus maximus or any muscle/inner muscle to induce body contouring and/or body shaping effects and fat burning. It can be treated. Additionally, shortened and/or stretched muscles may be stretched. The patient's physical fitness may also be improved.

The treatment may include at least 500 magnetic pulses per treatment, or at least 1000 magnetic pulses may also be applied per treatment. Alternatively, the treatment may comprise at least 2000, preferably at least 5000, more preferably at least 10000, even more preferably at least 20000 pulses and most preferably at least 50000 pulses per treatment. Treatment may include up to 200000 pulses per treatment.

According to one use case, a time-varying magnetic field may be applied to various pulse sequences called protocols. A protocol may include multiple sections including trains and bursts. A section may contain specific train periods, burst periods, or section periods. Sections include treatment parameters such as repetition rate; number of impulses in the train; The duration of the burst or the modulation of the time-varying magnetic field can be varied, i.e. changing the treatment parameters over time, alternatively the sections can be repeated or alternated. Modulation of the amplitude of the time-varying magnetic field, i.e. modulation of the magnetic flux density, may be used. Modulation of magnetic flux density can be interpreted as varying the amplitude of magnetic pulses to create an envelope. Different envelopes are perceived differently by patients. Treatment results may vary depending on protocol. The protocol may include at least two bursts or sections that differ from each other in flux density, repetition rate or impulse period.

The train comprises a plurality of subsequent magnetic pulses, ie at least two pulses. A burst contains one train and a period of time when no magnetic field is generated. A burst consists of a first time period and a second time period. At least one muscle contraction may occur during the first time period. Trains can last at least 4, 8, 25, 100, 200, 250, 300, 500 ms or 1, 2, 4, 5, 7.5, 10, 12.5, 15 seconds or more. Trains can likewise last tens of seconds. Exemplary treatments may include at least 2, 5, 10, 25, 50, 100, 250 or 500 bursts. Alternatively, the treatment may be in the range of 15 to 25000, preferably in the range of 40 to 10000, more preferably in the range of 75 to 2500, even more preferably in the range of 150 to 1500, most preferably in the range of 300 to 750. It can contain a range or multiple bursts up to 100000. The time between two subsequent trains may be at least 5, 10, 50, 100, 200, 500, 750 ms. Alternatively, the time between two subsequent trains, i.e. the second time period, may last for several tens of seconds, such as 1, 2, 2.5, 5, 7.5, 10, 15, 20 seconds or more.

The repetition rate in subsequent bursts may be increased/decreased incrementally in increments of at least 1, 2, 5 Hz or more. Alternatively, the flux density may be varied in subsequent bursts, such as incrementally increasing/decreasing in increments of at least 1, 2, 5% or more of the previous burst.

Figure 9 shows an exemplary trapezoidal envelope. The vertical axis can represent magnetic flux density. The horizontal axis can represent time. The trapezoidal envelope is a train of pulses of three sub-periods, where the first sub-period (T _R ) is the time at which the magnetic flux density increases, referred to as the increasing transient time, i.e. the amplitude of the magnetic flux density can increase. The second sub-period (T _H ) is the time having the maximum magnetic flux density, that is, the amplitude of the magnetic flux density may be constant. At least two magnetic pulses are generated during time T _H , preferably a plurality of magnetic pulses are generated. The third sub-period (T _F ) is a time when the magnetic flux density decreases, that is, the amplitude of the magnetic flux density may decrease. The sum of T _R , T _H and T _F may be the trapezoidal envelope period.

The first section may include a repetition rate ranging from 80 to 150 Hz. The train may be unmodulated, i.e. the envelope may be rectangular. The train period may range from 1 to 1000 ms, more preferably from 5 to 500 ms, more preferably from 10 to 100 ms, and most preferably from 15 to 45 ms. The train may be followed by a relaxation cycle for a time period in the range of 2 to 2500 ms, more preferably in the range of 10 to 1200 ms, even more preferably in the range of 20 to 250 ms, most preferably in the range of 35 to 155 ms, i.e. The time-varying magnetic field is not applied to the patient during the relaxation cycle. The total time period of the burst may be in the range of 3 to 3500 ms, more preferably in the range of 15 to 1700 ms, even more preferably in the range of 30 to 350 ms, most preferably in the range of 50 to 200 ms. . Section duration may range from 3 to 10 seconds or up to 30 seconds. Sections may preferably be repeated at least 2 times, more preferably 5, 10 or up to 30 times. The amplitude of the magnetic flux density can advantageously increase in subsequent sections.

The second section may include a repetition rate ranging from 10 to 30 Hz. The train can be modulated with a trapezoidal envelope in the amplitude of the magnetic flux density. The trapezoidal envelope may include increasing transient time periods in the range of 250 to 1000 ms. After the amplitude of the magnetic flux density reaches a maximum value, a magnetic field can be generated with a constant amplitude for a time in the range of 0.5 to 3 seconds. The magnetic flux density amplitude may then decrease to zero for a time in the range of 0.5 to 4 seconds. Thereafter, a relaxation cycle may follow for a time ranging from 1 to 5 seconds, i.e. no time-varying magnetic field can be applied to the patient. The total time period of the burst may range from 2.25 to 13 seconds. Section duration may range from 30 to 150 seconds.

The third section may include a repetition rate ranging from 25 to 60 Hz. The train can be modulated with a trapezoidal envelope in the amplitude of the magnetic flux density. The trapezoidal envelope may include increasing transient time periods in the range of 250 to 1000 ms. After the amplitude of the magnetic flux density reaches a maximum value, a magnetic field can be generated with a constant amplitude for a time in the range of 0.5 to 5 seconds. The magnetic flux density can then be reduced to zero for a time ranging from 0.5 to 4 seconds. Thereafter, a relaxation cycle may follow for a time ranging from 2 to 10 seconds, ie no magnetic field can be applied to the patient. The total time period of the burst may range from 3.25 to 20 seconds. Section duration may range from 50 to 250 seconds.

The fourth section may comprise a repetition rate of up to 5 Hz, more preferably up to 2 Hz or on the order of 1 Hz. The time period of the fourth section may range from 10 to 120 seconds.

The flux density of the train in subsequent bursts may increase. The increment in magnetic flux density between subsequent trains may range from 1 to 50% of the maximum allowable value of magnetic flux density, for example preferably about 5%, more preferably about 10% and most preferably about 15%. there is.

Magnetic treatment can be combined with adjuvant treatment methods. Examples of adjuvant treatments include the application of mechanical waves, such as acoustic waves, ultrasound or shock wave therapy; or electromagnetic waves, for example radiofrequency, such as strong pulsed light or laser therapy, or diathermy or phototherapy; or mechanical treatment, such as positive or negative pressure, rollerball, massage, etc.; or thermal treatment, such as cryotherapy, or electrotherapy methods; or mesotherapy methods and/or any combination thereof. Combined methods using magnetic fields and optional adjuvant treatment methods can be applied to the patient by one applicator, for example coils and different energy sources (cooling, mechanical, optical and/or RF waves) in one applicator. There may be. The magnetic field may be generated by a treatment device that is separate from other treatment devices that provide an adjunctive treatment method. The first applicator may include a coil and a second applicator containing an adjuvant treatment may be attached to the first applicator or vice versa. Alternatively, the first applicator containing the coil and the second applicator containing the adjuvant treatment may be attached to a common mechanical holder, such as a platform.

Depending on the method mentioned, treatment may be, but is not limited to, continuous, pulsed, random or burst. The impulse may be, but is not limited to, a single-phase, multi-phase, biphasic, and/or static magnetic field. In a preferred application, the magnetic impulse may be biphasic, i.e. consisting of two phases, preferably two phases, positive and negative.
